Which of the following does not form oxide on heating a. ZnCo3 b. CaCo3 C. Li2co3 D. Na2co3
Question
Which of the following does not form oxide on heating a. ZnCo3 b. CaCo3 C. Li2co3 D. Na2co3
Solution
To determine which of the given options does not form an oxide on heating, we need to consider the chemical properties of each compound.
a. ZnCO3 (Zinc Carbonate): When heated, it decomposes to form Zinc Oxide (ZnO) and Carbon Dioxide (CO2). Therefore, ZnCO3 does form an oxide on heating.
b. CaCO3 (Calcium Carbonate): When heated, it decomposes to form Calcium Oxide (CaO) and Carbon Dioxide (CO2). Therefore, CaCO3 does form an oxide on heating.
c. Li2CO3 (Lithium Carbonate): When heated, it decomposes to form Lithium Oxide (Li2O) and Carbon Dioxide (CO2). Therefore, Li2CO3 does form an oxide on heating.
d. Na2CO3 (Sodium Carbonate): When heated, it decomposes to form Sodium Oxide (Na2O) and Carbon Dioxide (CO2). Therefore, Na2CO3 does form an oxide on heating.
Based on the above information, all of the given options (a, b, c, and d) form an oxide on heating. None of them do not form an oxide.
